Abstract
A system for remediation of perfluoroalkyl substances (PFASs) has a multiplicity of β-cyclodextrins (β-CDs) and/or modified β-CDs combined with a vehicle additive, and a delivery device. Modified β-CDs can contain a single amine functionality at a single primary carbon or single secondary carbon of the β-CD. The vehicle additive can be powdered activated carbon (PAC). The delivery device is a column, a pouch, a packet, or a sheet that can permit the contacting of a fluid environment with the β-CDs and vehicle additive. The system of remediation can be used for a fluid environment or for biological organisms. CD-based fluorescent sensors can detect PFASs in the environment.
